Santorum: Parents should run schools

[True Federalist (진정한 연방 주의자)]

I don't much care for the USDoE myself, but I consider its functions to be constitutional.  It implements its demands not via "you must do this whether you want to or not", but "if you want this money, then you must do this".   Federal spending on education falls squarely under the authority of the general welfare clause.

Separation of church and state. Look it up, it's in that Constitution you love to talk about.

That's actually a point that can be used in favor of vouchers.  By allowing the decision of the type and quantity of religious content, a child receives in their schooling to be up to the parent through their choice of school, there is no Constitutional bar.  As it is now, the public schools are skewed in favor of the viewpoint that religion is unimportant.

For the government to opt for atheism is as much an establishment of religion as the converse.

No. No. No.

Nothing is not something. Likewise, no religion is not a religion.

Fine. It's still a competing belief system.  Don't be so pedantic because the founding fathers had as much difficulty in imagining a belief system without religion as they did in imagining that we'd add a third military branch in addition to the army and navy.
